San Francisco 49ers LB Darius Fleming (knee) and DL Cam Johnson (knee) were each part of the rehab group in workouts Tuesday, June 12, wearing wraps on their left knees. Fleming has a torn anterior cruciate ligament, and he likely will miss the season.

San Francisco 49ers head coach Jim Harbaugh indicated LB Cam Johnson (undisclosed) recently underwent a minor surgical procedure. Harbaugh did not mention the area but it is believed to be his knee since he dealt with a knee injury in college last season.
